CMake is a very powerful cross-platform system for generating automated build systems. On Unix it builds makefiles which it then runs, on windows, it normally builds projects for Visual Studio (though it can also build Makefiles using MinGW on windows).
CMake is used to build each of the wrappers for CoolProp.
To install CMake, please visit CMake.org or install
it through your systems package manager. For Mac OSX, you can use
brew install cmake. If you do not like that, you can also install
it from the official binary release, you have to start it as
super user to be able to install the symlinks in the system path. Run:
once and choose Tools->Install For Command Line Use from the menu. Alternatively, you can run these commands from a normal terminal session:
sudo ln -s /Applications/CMake.app/Contents/bin/ccmake /usr/bin/ sudo ln -s /Applications/CMake.app/Contents/bin/cmake /usr/bin/ sudo ln -s /Applications/CMake.app/Contents/bin/cmake-gui /usr/bin/ sudo ln -s /Applications/CMake.app/Contents/bin/cmakexbuild /usr/bin/ sudo ln -s /Applications/CMake.app/Contents/bin/cpack /usr/bin/ sudo ln -s /Applications/CMake.app/Contents/bin/ctest /usr/bin/
